SPRAYING DEVICE.

SPECIFICATION forming part of Letters Patent No. 471,141, dated March 22, 1892.

Application filed July 6. 1891- Serlal No. 398,514. (No model.)

To all whom it may concern:

Be it known that I, I/VILLIAM J. RUFF, of Quincy, in the county of Adams and State of Illinois, have invented a new and Improved Spraying Device, of which the following is a full, clear, and exact description.

The invention relates to spraying devices, such as shown and described in the Letters Patent of the United States No. 453,918, granted to me June 9, 1891.

The object of the present invention is to provide a new and improved spraying device, which is very simple and durable in construction, arranged to facilitate the mixing of the beer or other liquid with the sprayed liquid, and to prevent clogging of the device.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement, and Fig. 2 is a sectional plan view of the same on the line 00 cc of Fig, 1.

The improved spraying device is provided with a casing A, formed with a larger upper compartment B and a smaller lower compartment 0, the joint between the twobeingformed by a valve-seat D. The lower compartment 0 is formed with an inlet-opening E, adapted to be connected with a pipe or other means for conducting the liquid to be sprayed into the casing A.

On the lower end of the compartment 0 is I formed an outlet F, 011 which is held a nozzle G, formed with a central opening G, leading into the cone-shaped cup G In the opening G of the nozzle G is adapted to pass a coneshaped valve I-I, somewhat less in diameter than the diameter of the opening G, so that the liquid can pass from the compartment 0 through the space between the edge of the valve and the inner surface of the opening G into the cone-shaped cup G from which the liquid passes in sprays into the air, and is thereby cooled and aerated. The valve H is fastened on the lower end of a valve-stem I, extending through a casing A and fastened to a double piston-valve J, of which the larger part J is fitted to slide in the compartment 13 and the smaller part J extends into the compartment 0. The joint between the two- 'a tight connection of the piston in the compartment B. The upper end of the valvestem I extends loosely through a bearing in the cap K, closing the upper end of the compartment B. The extreme outer end of the valve-stem I is provided with a thread I, on which screws a nut L, resting on the cap K and serving to adjust the stem I within the casing, so as to hold the valve H in the proper position relative to the opening G in the cup G A handle I is secured on the upper end of the valve-stem for conveniently turning the same.

On the valve-stem I is coiled a spring N, pressing with one end onto the piston J and with its other end against the under side of the cap K. An opening I is formed in the valve-stem within the compartment B, the said opening leading to a central recess 1 extending downward in the valve-stein to open into the cone-shaped cup G In the compartment B is also arranged an inlet-opening 0, adapted to be connected with a steam or water supply to clean the apparatus whenever necessary.

The operation is as follows: Then the device is in the normal position, as illustrated in Figure 1, the liquid can flow through the openingE into the compartment 0, and from the latter, through the outlet F, past the valve H into the nozzle G to be sprayed, as previ ously described. In case small particlessuch as hops or other substancespass with the liquid into the compartment 0 and clog the valve 11 in the opening G, then afurther escape of the liquid from the compartment 0 is prevented, and consequently the pressure of the entering liquid is exerted against the small part of the piston-valve J so that the latter is forced upward against the tension of the spring N. It is understood that when the liquid presses against the small part of piston and raises it ever so slightly, the seat of piston J will be exposed to the pressure of the liquid, and the seat being of a larger area than the small part of piston J, it fol lows that the pressure then exerted 011 the spring N is greater than it was, which will compress the spring much quicker and cause the piston to be rapidly thrown upward,withdrawing the valve II at the same time, when the clogging matter will pass out at once with the liquid, (to be sprayed,) thereby quickly relieving the pressure and causing the piston to seat quickly, as the pressure below is so quickly diminished by the valve opening the orifice wide, caused by the rapid withdrawing of same through increased piston area. As soon as the liquid flows freely through the opening G the pressure against the piston-- valve J ceases, so that it is returned to its normal position by the action of the spring N. The downward movement of the piston-valve J moves the valve H back to its normal position in the opening G, and the spraying again proceeds in the manner above described.

As shown in the drawings, the area of spraying is in a circle; but it can be changed to a quarter or half inch by inserting a stem with the valve II of, a diiferent form and changing the form of the nozzle G, which can be easily unscrewed and another put in place. This changing is done where it is necessary to get closeto the edge of the vessel into which liquid is sprayed. By forming the piston-valve with the different-sized parts J and J it is forced back quickly to its normal position as soon as the pressure of the liquid within the compartment 0 ceases, as the area of the upper part J is so much larger than the area of the lower part J and is thus more exposed to atmospheric pressure. Thus a lighter spring N can be employed to assist in returning the piston to its seat.

The valve-steml is made partly hollow, so that any liquid which may accidentally get into the upper compartment B can quickly run through the opening I and central passage I" to the nozzle G, thereby keeping the apparatus clean and mixing the beer or liquid thoroughly with the other spraying-liquid. The connection of the upper compartment B with the nozzle G by means of the central passage 1 also permits of conveniently cleaning the upper compartment by steam, water, or other means charged into the compartment through the inlet 0. The inletopening E is also connected with the steam, water, or other supply, so as to clean the lower compartment simultaneously with the upper compartment B whenever deemed necessary. The nut L serves for adjusting the stem I and valve ll, so that coarser or finer liquid can be sprayed by the device.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a spraying device, the combination, with a casing formed with two different-sized compartments, of a spraying-nozzle held on the end of the smaller compartment, a springpressed piston-valve held in the said casing above the inlet-opening thereof and adapted to be seated on the part of the casing between the two compartments, and a valve carried by the said piston-valve and projecting into the opening of the spraying-nozzle, substantially as described.

2. In a spraying device, the combination, with a casing formed with two ditterentsized compartments, of a spraying-nozzle held on the end of the smaller compartment, a pistonvalveheld in the said casing above the inletopening thereof and adapted to be seated on the part of the casing between the two compartments, a valve carried by the said pistonvalve and projecting into the opening of the spraying-nozzle, and a spring pressing on the said piston-valve, substantially as shown and described.

3. In a spraying device, the combination, with a casing formed with two different-sized compartments and a valve-seat between the two compartments, of a spraying-nozzle held on the smaller compartment, a piston-valve held in the said casing and formed with a larger and smaller part, a valve between the two parts and adapted to be seated on the said valve-seat, and a spraying-valve supported from the said piston-valve and projecting into the opening of the spraying-nozzle, substantially as shown and described.

4. In a spraying device, the combination, with a casing having two compartments and provided with a spraying-nozzle, of a pistonvalve fitted to slide therein, a stem secured in the said piston-valve and formed with a central passage and opening connecting with the interior of the said casing above the said piston-valve to drain the upper compartment, and a valve on the lower end of the stem and projecting into the opening of the sprayingnozzlc, substantially as shown and described.
